SWIVEL ROPE-SOCKET.

lowing the leaded end of the wire rope to be removed and replaced without cutting the rope; to insure that the bearings of the swivel shall be kept clean and well oiled and free from steel cuttings that may result from the contacting surfaces; and to permlt the swivel stem to become detached from the rope socket box when the working valves in the pump become sanded in the pump barrel.

Referring to the accompanying drawings, Figure 1 is a central vertical section of a rope socket and swivel embodying my invention; Fig. 2, a side elevation. of the swivel stem; Fig. 3, a top plan view of Fig. 2; Fig. 4, a side view of the swivel bearing; Fig. 5, a top plan thereof; and Fig. 6, a bottom plan thereof.

On the drawings, 1 represents the barrel, threaded internally at each end. .The rope seat 2, which is tubular is screwed into the upper end of the barrel 1 and provided with the integral collar or shoulder 3 in engagement with the end of the barrel. The rope seat is divided into lateral halves on the line 1, so that when the rope seat is screwed out of the barrel the halves thereof may be separated and removed entirely from the rope which normally extends down through the seat 2 and into the space in the barrel below, where the wire-rope is variously bent and leaded. The inner wall at the lower end of the seat is tapered upwardly in the usual manner to provide a wedging seat for the leaded end of the rope.

The swivel support 5 is screwed into the lower end of the barrel 1 and is provided with the stop shoulders 6 which contact with the end of the barrel. The support 5 has a central longitudinal round hole 7 Above the screw threads thereon the support 5 is provided with the open-ended slots 8 which extend transversely entirely through the Specification of Letters Patent.

wall of the same, but from the top of the threads the slots 8 are continued as grooves in the wall of the hole 7. At the bot-tom of the support 5 the grooves open outwardly by the ports 9. The support 5 is divided longitudinally into halves, 10 indicating the dividing line which may coincide with one. side of the slot 8. The support 5 is flattened at 10, 10 so that a wrench may be applied thereto for screwing the same intoand out of the barrel.

Within the swivel support 5 is the round shank 11 of the swivel-stem. The upper end of the shank has thereonthe swivel head 12 which has a larger diameter than the shank, its lower end being fiat and resting on the Hat upper end of the support The head 12 is provided with longitudinal slots 13 which extend from end to end of the head and are open at the periphery thereof.

In the rope socket chamber 14, I provide one or more ports 15 through the barrel 2. little above the head 12.

The lower end of the swivel-stem extends down into the tubular socket-box 16 to which it is secured by a suitable number of rivets 17. The upper end of the box 16 abuts the lower end of the swivel support 5, and

nitely.

If for any reason the working valves below the device shown become sanded in the barrel or for any other reason the parts below the socket-box 16 are stuck in the well, the rivets may be cut or sheared off by the whipping or hard pulling on the wire line connected to the socket, so that it will not be necessary to pull the sections of tubing from the well over the wire line.

I claim 1. In a rope-socket, a barrel, a tubular rope-seat secured to.one end of the barrel, a swivel-support secured to the other end of the barrel, and a swivel-stein rotatable in the said support and having a swivel-head, bearing on the upper end of the said support,

a, 4 animate the said swivel-support and swivel-head having longitudinal slots, the barrel and I the slots in the swivel-support having ports,

* head, and one or more longitudinal slots in the said support, the barrel having a port through its Wall above the said swivel-head, and the said swivel-support having a lateral portfor each slot.

3. In a rope-socket, a barrel, a rope-seat on one end thereof, a swivel-stem supported by the other end, a socket-box into which the lower end of the swivel-stem projects, and

rivets extending through the sooket box and swivel-stein to connect them together, the,

rivets being sufliciently large to perform the work ordinarily required in use, but suficiently small to be sheared ofi' when the swivel stem is drawn up with-aforce exceeding predetermined value above that ordinarily applied in use. i
